Abstract

Descoping is the strategic abandonment and/or weakening of objectives. It is required whenever limited resources preclude satisfactory attainment of all those objectives. Potential causes of the need for descoping are numerous, and descoping is a recurring phenomenon during project planning and development. We present an approach which facilitates descoping. It is founded upon a quantitative model of requirements attainment, resource consumption, and risk. Features of this model allow for the representation of interactions between objectives. Measures derived from this qualitative model support the identification and evaluations of descope options. Tool support for the model gives assistance to users in making their descope decisions.
